| 目的 分析阻尼参数对共振峰抑制与反共振隔振有效频率范围的影响。方法 在主减共振梁上安装阻尼器，改变阻尼大小进行仿真分析。结果 随着阻尼系数的增大，共振峰值逐渐降低，反共振点频率基本不变，隔振效率有所下降，有效隔振效率范围有所拓宽。建议把阻尼大小设为0.01最为有效。结论 通过安装阻尼器并改变阻尼大小可以有效地调节减震效率及反共振隔振有效频率范围。 |

| Objective To analyze influences of damping parameters on effective frequency range of formant suppression and anti resonance isolation. Methods A damper was installed on the main resonance beam, and the damping size was changed for simulation. Results With the increase of damping coefficient, the peak value of resonance gradually decreased; the frequency of the anti resonance point was basically unchanged; the efficiency of vibration isolation decreased; and the effective range of isolation efficiency was widened. It is suggested that the damping size of 0.01 was the most effective. Conclusion The damping efficiency and the effective frequency range of anti resonance isolation can be effectively adjusted by installing dampers and changing the damping size. |
